Agree, some truth to it, and remember the Elephant situation.

I think in one of them they put in Big mother's to control the situation.

Re crocs, fights still occur as young one's try to knock off big one's. When feeding crocs, we see one particular male that tries to show it's dominance and pushes the issue a bit until the really big one comes along. We are expecting the really big one to eventually get knocked off - in fact a few years ago I spent a few hours looking for his floating body as it was thought he had been killed.
